Calling the ResumeLayout method forces an immediate layout if there are any pending layout requests.

The SuspendLayout and ResumeLayout methods are used in tandem to suppress multiple Layout events while you adjust multiple attributes of the control. For example, you would typically call the SuspendLayout method, then set the Size, Location, Anchor, or Dock properties of the control, and then call the ResumeLayout method to enable the changes to take effect.

The SuspendLayout calls must be equal to zero before ResumeLayout can be successfully called.
